I play these stakes, and still have much learning to do but here's my .02c

Preflop is super loose, i would insta fold that hand. Against a decent solid player I don't think u will find a fold often enough and heads up in position villain will call i would think 90% of the time. I know i would. Playing OOP sucks with non nutty hands, you will only ever win a small pot and lose big ones.

Flop Cbet is fine considering your preflop raise. Opp calls. A call reduces the likelihood of a set and massive combo draws in his range. So he is either calling for a safe turn, or floating you, with a small chance that he is holding 33, tt, etc.

Turn Turn cbet is fine i think again (balance against floats) but would fold to the reraise. Our hand is a dog to everything but air in his re raising range. I also don't like the call personally. Allows him to put you on the diamond draw and you are unlikely to get paid on the river if you hit and only called if your beat. Since If you had a combo draw you would have definitely jammed the turn. This is a jam or fold spot for me.

River c/fold I don't like the lead out. Never called by worse ever. and for 1/3rd pot you don't have much fold equity. At the very least villain has jtxx or j3xx, combined with hand narrowing and a non diamond river its an ez bluff catch.

Looks good.
If he made it 3x on the turn, this play doesn't seem anywhere near as good. He just doesn't rep much of the way in semi bluffs and looks exactly like a made hand trying to protect which opens this door up for you to call and check all the times you hit expecting him to check back and to bluff all the cards that change the board that don't improve your hand, like this one.

pre flop is fine, i may fold the ss-version vs some.

re the river bluff: i wouldnt recommend this without a read that villain folds a lot here. our bluff needs to work almost 33% of the time but in my experience itll work closer to 10-20% vs most.

if were not sure whether to bluff the river or not, and we are indifferent we may as well try to be balanced. with this sizing otr, we would need more than 75% of our bets to be value bets.

i cant get the HH to work in pokerjuice and i dont know enough about your range to say for sure. we are repping 87/Q8/KQ/99 but im not sure we have enough of those value bets since there are so few Q8/87/99 in our b/c range ott. we do however have both a K and an 8 blocker which is better than most of our bluff candidates otr.

post the complete raw HH here and ill run the RD/BC-module in pokerjuice.
